Finally decided to undertand this part: Vim documentation: pattern
\m is magic, \M is nomagic. \m/magic is the default.\v is verymagic, \V is very nomagicHandy table from the documentation:
Examples:
after: \v \m \M \V matches
'magic' 'nomagic'
$ $ $ \$ matches end-of-line
. . \. \. matches any character
* * \* \* any number of the previous atom
() \(\) \(\) \(\) grouping into an atom
| \| \| \| separating alternatives
\a \a \a \a alphabetic character
\\ \\ \\ \\ literal backslash
\. \. . . literal dot
\{ { { { literal '{'
a a a a literal 'a'
Practically:
\v/verymagic - almost everything has a special meaning (numbers, letters and _ are the only ones parsed as-is)\V/verynomagic - almost nothing has a special meaning, everything interpreted as-is EXCEPT \A Vim Guide for Adept Users has these nice tips that I’ll stick to:
My advice in this madness: remember that very magic will allow you to use every regex metacharacter without escaping them, and that very nomagic oblige you to escape these metacharacters to use them.
and
I propose this simple rule:
- When you need a regex, use “very magic” by adding \v before your pattern.
- When you don’t need a regex, use “very nomagic” by adding \V before your pattern.
It also has this nice list:
\s or [:blank:] - whitespace characters.
[A-Z] or \u or [:upper:] - Uppercase.
[a-z] or \l or [:lower:] - Lowercase.
[0-9] or \d or [:digit:] - Digits.
\_ - Character class with end of line included.

rsync.net is a nice no-nonsense offering. They have special prices for borg backups: Cloud Storage for Offsite Backups - borg support

:fill works not just for moving stuff, but also tracking!
If I tracked A from 11:00 to 11:23 and now it’s 11:30, I can do timew track 2min B :fill - it will create B from the end of the previous one until now, so 11:24 - 11:30.
<C-R> gets vi-mode into search mode, after returning to Normal mode n/N work just as expected to do a case-insensitive search of similar things in history
How to Change Your Default Google Account on Mac or PC says that the first one I log into will be the default one.
Webmin is cool and allows to move iptables rules!
A top-level folder can be excluded, but any of the folders inside it can be marked as something else and that will override the parent! Very sensible decision actually, when I think about it

autocmd VimLeave * call system("xclip -selection clipboard -i", getreg('+'))
Here vim’s system() command is interesting:
If you pass a second argument like this, Vim will write it to a temporary file and pipe it into the command on standard input.2
In any case, I should really write some alias to be able to use xclip and friends by passing parameters to them, not piping stuff - makes any kind of scripting with them much harder.
And to finish, Learn Vimscript the Hard Way seems to be still an excellent introduction to vim itself, even without the scripting part.
ag/grep output only capturing groupsThis3 describes how to get ag to output not the match, but only a specific capturing group inside it:
ag -o 'https://\K.*?(?=")'
It uses PCRE features to remove stuff from before and from after the match:
\K resets the match start(?=") sets the end to " - here, " is what should be after the match, but will not be included in it.Related is Learn PCRE in Y Minutes. PC in PCRE stands for “Perl Compatible”.
PCRE can be enabled in grep by doing grep -P, and it’s the default in ag.
Parametrization · iterative/dvc Wiki is an experimental feature.
Allows to call parameters directly, such as:
stages:
build:
foreach: ${models}
do:
cmd: >-
python script.py
--out ${item.filename}
--thresh ${item.thresh}
outs:
- ${item.filename}
as opposed to getting your program to read parameters.yaml
IPSet set structures: wiki.ipfire.org - IPset
To create an ipv6 ipset that supports domain ranges, we need the hash:net one:
ipset create my6 hash:net family inet6
Nice subnet calculators:
iptables doesn’t do ipv6, but ip6tables does, seems to be installed by default along with vanilla iptables. Commands seem to be identical.
iptables-save > some_output_file to save them to a file (this alone doesn’t make it persist reboots)iptables-persistent does what is says on the label,1 for rules being saved in:
/etc/iptables/rules.v4/etc/iptables/rules.v6ipset save > output_file
ipset save -f output_file
ipset restore -f output_file
ipset restore < output_file
The output files it generates seem to be the exact commands without the leading ipset ?
Looked into yunohost’s recommendations, there’s a best practice.2 Created a shell script that does ipset restore -f file and then runs the iptables commands, put it into /etc/yunohost/hooks.d/post_iptable_rules/99-specific_rules. Survived a reboot, mission accomplished.
> mktemp /tmp/somescript.XXXX
/tmp/somescript.6Zxi
mktemp creates random files with a set format, replacing the XXX with random characters, and returns the filename (+ can also create directories). Cool!

> friends add activity three days ago: Some activity three days ago <<<
Activity added: "2021-05-30: Some activity three days ago"
# also works:

As with taskwarrior, things can get arbitrarily shortened as long as they remain unique!
friends a ac "some activity" (you can add both an activity and an alias)
Found this: How to use collections on addons.mozilla.org | Firefox Help
TL;DR create an extension collection on Firefox’s website, then from Fennec or Firefox Nightly they can be installed! Wooooohooo!
Also TIL about Fennec - seems like a Firefox fork without features that are ‘considered harmful’
